Hello Or, Will this API ever be supported by other Mellanox RDMA drivers than mlx5, e.g. mlx4 ? Will this API ever be supported by a Mellanox HCA that supports RoCE ? Additionally, do you perhaps know whether any other RDMA vendors have plans to implement this API for their RDMA HCA's ? Drivers like the iSER and SRP initiator and target drivers have been implemented on top of the RDMA API and support all hardware that implements the RDMA API. Since this patch series adds support for the indirect fast memory registration API for mlx5 only this means that adding support for this API in block storage drivers also means adding a fall-back path for RDMA drivers that do not have support for this API. That will make these block storage drivers harder to maintain, which is something I would like to avoid.
